B1349 F4 produces the Di Tuo Bi Bay bronze M79250BM wristwatch.

【Case】The watch size is 43 millimeters. As a pioneer in bronze materials, it emphasizes meticulous details. The [aluminum bronze] material used is perfectly suitable—its oxidation process is slow, and it does not produce green rust; moreover, it has higher hardness and greater weight. This ensures that the watch retains its authentic appearance after oxidation, preserving its unique style. 【Bracelet Clasp】The hand-stitched Italian cowhide material is treated with a matte finish, adding a vintage appeal. It complements the aluminum bronze clasp perfectly. 【Movement】It uses an upgraded movement, eliminating the awkward situation of empty date positions. When classicism reignites, the Dirtbike Bronze Biwan M79250BM continues to write a new legend, with its time-tested quality. The robust nature of the Biwan series serves as a declaration of style and a tribute to vintage aesthetics. Made entirely from original aluminum bronze material, it develops a unique copper color over time. Every trace becomes a timestamp of your journey—making the watch a companion on your path to success.
